Integrated kubernetes with jenkins and run the command in Jenkins file kubectl create -f deployment.yaml --validate=false and getting the error:

unable to recognize "deployment.yaml": no matches for extensions/,Kind=Deployment

But if I run the same command in terminal I am able to deploy my image. deployment.yaml file is given below

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: appname
spec:
  template:
    metadata:
      labels:
        app: appname
    spec:
      containers:
      - name: appname
        image: appname
        imagePullPolicy: IfNotPresent
        ports:
